SPRING SUSPENSION FOR MOTOR VEHICLES.

Application filed April 26, 1922. Serial No. 556,794.

To all whom it may concern Be it known that Hanmx N. GARsoN, a subjectof Norway, and THORVALD N. GAR- SON, a citizen of the United States,both residing in the cit of New York, county and State of New ork, andwhose post-office address is 30 Church Street, New York city,

. have invented certain new and useful Improvements in SpringSuspensions for Motor Vehicles, of which the following is aspecification.

Our improvements relate more particularly to the type of suspensionwhich is the sub ect of our Letters Patent No. 1,412,733 of April 11,1922, and particularly to the rocker-connections between the frame, thesprings and the axle, to means for preventing side-sway, and otherfeatures hereinafter more particularly referred to.

The invention will be understood by reference to the accompanyingdrawings, in which- Fig. 1 is a lan view of an automobile chassisembodylng the invention, and

Fig. 2 is an elevation of the same.

Fig. 3 is a fragmentary, partly sectional elevation of a modification inthe connections between the rockers and the springs.

Fig. 4 is a longitudinal sectional view ofthe slide contact memberfor aload-carrying spring and its complementary bumper spring, mounted inposition upon a tubular side-frame member.

Fig. 5 comprises detail views of the slidecontact member shown. in Fig.3.

Fig. 6 illustrates in plan and elevation a section of the front axlecarrying the abutment roller. 7

Fig. 7 is a fragmentary plan View of the front transverse frame memberprovided with the opposed vertical guide walls for the abut-ment rollerof the front axle.

In the embodiment shown in Figs. 1, 2. 4, 6 and 7 of the drawings thechassis comprises the tubular longitudinal frame members 1 connected attheir rear ends by the rear cross-frame member 2 and at their front endsby the front transverse frame member 3, the latter being formed as aforwardly projecting U-shaped member having at each longitudinal sidetwo depending sleeves 3 3 which receive the appropriate longitudinaltube 1. The upper horizontal faces a, b, c, afi'ord adequate support fora radiator and the front section of a body,

(not shown); and the U-shaped member 3 as a whole affords a three pointsus ension for the engine, as shown in Fig. 1. he upwardly extendingarms d of the rear cross frame member 2 serve as supports for the rearof the body.

Each end of each tubular side frame member 1 projects slightly beyondits connecting cross frame member and has bolted thereon the upper andlower halves of a socket member 4 which embraces a ball carried at oneend of a rocker 5 which at its opposite end is rigidly connected to theappropriate axle. At the rear of the chassis the axle is maintained inalinement, and side-sway resisted, by means of the sway rods 8intermediate the axle and collars 6 free for oscillations in stud boltssecured to projections 7 of the rear cross frame member 2.

The front axle carries a centrally disposed roller 7 which rotates upona studscrew 8 and in the relative vertical move ment of thechassis-frame and the axle this roller is guided between the opposedvertically disposed guide-plates 9 carried by the front cross-framemember (Figs. 1 and 2). In this manner the front axle and frame aremaintained in proper alinement.

Each longitudinal tubular member carries two helical springs at eachside of the depending sleeve 3 of the front cross frame member. Eachinnermost spring 10 is a bumper spring while the outer springs 10 areload-carrying springs, each set comprising one bumper and oneload-carrying spring engaged by an abutment-collar 11 on a sleeve 11(Fig. 4) mounted on an appropriate longitudinal tubular member 1. Thiscollar 11 is formed with a depending apertured lug 12 to which ispivotally connected one end of a link 13 which at its opposite end ispivotally connected to the depending arm 5 of a rocker 5.

In the operation of the device, it will be understood that theload-carrying springs 10 will be so proportionedto the weight of thechassis that the springs will act through the collars 11 links 13 androckers 5 to maintain the said elements substantially in the positionshown in Fig. 2 when the chassis is at rest. When the chassis is set inmotion and a wheel passes over an obstruction and is elevated, itsrocker pivotally moves against the resistance of the appropriateload-carrying spring 10* through the move- ,ment of link 13 and sleeveand collar 11, 11".

en the force which thus swings the rocker is dissipated and the rockeris swung back into normal position by the return movement of sleeve andcollar 11, 11*, the latter will be controlled against undue movement bybumper sprin 10, which thus acts as a shock absorber. he provision of asleeve of substantial bearing surface in conjunction with the collarinsures move ment of the latter without binding on the tubular framemember and permits a single point of connection for the inner end oflink 13.

In the modification illustrated in Figs. 3 and 5 the ball and socketconnection between the rocker and the frame is dispensed with, ahorizontal pivot stud 14 being employed. The connection between therocker and the axle comprises a pivot stud 15 carried by the rocker andfitted within a sleeve 16 bolted to the axle in any suitable manner. Thelink 17 extends within the tubular longitudinal frame member 1 and isconnected with a pivot stud 18, the ends of the stud passing throughslots 19 in the member 1 and thence being secured within aperturesformed in the short sleeve 20 intermediate the load-carrying spring 1.0and the bumper spring 10. In this construction when one wheel rises overan obstruction and that end of the axle is elevated and then lowered,the axlesleeve 16 at the op posite end will oscillate upon its pivotstud 15 of the appropriate rocker.

Having described our improvements, what we claim and desire to secure byLetters Patent is 1. In a motor driven carriage a frame comprisinglongitudinal members and transverse connecting members, load-carryingsprings horizontally uided upon said longitudinal members, gout and rearaxles, sleeves adapted to engage said springs, a series of rockers eachhaving a ball and socket connection at one end with the frame andsecured at the opposite end to an axle,

and a link connecting each rocker with a sleeve.

2. In a motor driven carriage a frame comprising longitudinal membersand transverse connecting members, loadecarrying springs horizontallyguided upon said longltudmal members, front and rear axles, a series ofsleeves each guided upon a longitudinal frame member and having acontact member engaging a load-carrying spring, a series of rockers eachhaving a bal and socket connection at one end wlth the frame and securedat the opposite end with an axle and a link pivotally connecting therocker and sleeve.

3. In a motor driven carriage a frame comprising longitudinal membersand transverse connecting members, load-carrying springs horizontallyguided upon said longitudinal members, front and rear axles, sleevesupon said longitudinal members and adapted to engage said springs, aseries of rockers each connecting an axle and the frame, and guidingdevices intermediate an axle and the frame comprising a roller carr edby one of said members and parallel guide plates carried by the secondmember to cooperate with the roller, substantially as described.

4. In a motor driven carriage, a frame comprising longitudinal membersand transverse connecting members, the front transverse memberprojecting forwardl of the longitudinal members in U shap formation,load carrying springs horizontally supported upon said longitudinalmembers, connections intermediate said axles and the load-carryingsprings, opposed guide-plates carried by the front transverse framememher, and a roller carried by the axle in position to be controlled bysaid guide plates, substantially as described.

In testimony whereof, we have signed our names to this specification.
